/*!
  MFnGeometryFilter is the function set for geometry filters, the node
  that is the base class for deformers.  Geometry filter nodes include
  clusters, ffds, nonlinears, user-defined deformers, sculpts, wires
  and blendShapes.  The purpose of the geometry filter is to connect
  to the geometry that is deformed.  The geometry filter is
  independent of any algorithm that calculates the deformation.

  This function set provides methods for finding out which geometries
  are connected to geometry filter nodes.
